SME and normal call manager

[noc mcc]

what is the practical diference between SME and normal call manager?

[Chris Deren]

This is well described in SRND, in nutshell SME is CUCM without any devices registered to it, bridging leaf CUCM clusters and/or other devices such as Legacy PBXes, centralized Unity Connection, centralized CUBEs, any SIP systems, etc.  for centralized dial-plan and integration management.

Just adding to Chris' point. There is heck lot of difference in terms of Licensing though.

Hi,

As Chris mentioned this is well described in SRND. Here is a quote along with the link.

SME is the recommended trunk and dial plan aggregation platform in multi-site distributed call processing deployments. SME is essentially a Unified CM cluster with trunk interfaces only and no IP endpoints. It enables aggregation of multiple unified communications systems, referred to as leaf systems.

Cisco Unified CM Session Management Edition supports the following trunk protocols:

• SIP intercluster trunks
• SIP trunks
• H.323 Annex M1 intercluster trunks
• H.323 trunks to gateways
• MGCP trunks to gateways
